This is a hotfix to address an error with Image->Resize when used with certain image sizes.

NOTE for Windows 7, Windows 8.1, and 32-bit/x86 users: Paint.NET v4.3.x will be the last release(s) that work on Windows 7, Windows 8.1, or on any 32-bit/x86 version of Windows. It has become significantly more difficult and time consuming to support these lately, not very many people are using them, and I can no longer justify the cost and frustration of keeping support for these afloat. Starting with Paint.NET v4.4, only Windows 10 and 11+ will be supported, and only on 64-bit (x64 and ARM64). Updates for 4.3.x will be released on an as-needed basis until v4.4 is completed.

Changes since v4.3.9:

• Fixed an error with Image->Resize when using Nearest Neighbor resampling with certain image sizes

Since this is a hotfix, here what also changed in v4.3.9 compared to v4.3.8:

• Added a workaround for a bug in the latest Windows 11 Insider "Dev Channel" build 10.0.22567.0 that is causing a lot of crashes. Microsoft has a hotfix coming soon.
• Fixed a compatibility issue with the Shape Maker plugin that was preventing the ability to open or save shapes
• Fixed the precision of color channel values for images with transparency when using the Invert Colors or Black and White adjustments. Before, color values were reset to zero if the alpha channel was also zero.
• Fixed the rendering for Image -> Resize when using Nearest Neighbor. Sampling was off by 0.5 pixels, causing incorrect results. Reported here: https://forums.getpaint.net/topic/118703-incorrectoffset-nearest-neighbor-scaling-when-using-resize-dialog/
• Fixed a crash in the Quantize effect when Alpha Threshold was set to 0 and the image was completely transparent
• Updated the bundled AvifFileType to version 1.1.19.0. This updates the AOM version to 3.3.0. (thanks @null54!)

Enjoy!
